Changing the Hydraulic
Fluid
Service Interval:
Every 2,000 hours—
If you
are using the recommended
hydraulic fluid,
change the
hydraulic fluid.
Every 800 hours—
If you are not using the
recommended hydraulic fluid or have ever
filled the reservoir with an alternative fluid,
change the hydraulic fluid.
If the fluid becomes contaminated, contact your Toro
Distributor because the system must be flushed.
Contaminated fluid looks milky or black when
compared to clean fluid.
